(Betsy's Choice Sage) Life and botany have their beautiful mysteries. Betsy's Choice Sage is one of them. We aren't certain of the parentage or history of this tall, attractive, fast-growing sage. However, we are certain that we love its tubular, royal purple flowers. Hummingbirds do as well.
Some say that it is a cross between a Salvia guaranitica and a Salvia fulgens. Some hint at a S. gesnerifolia connection by comparing it to S. x 'Jeans Purple Passion'. Others draw comparisons between Betsy's Choice and S. Amistad which may possibly be related to S. guaranitica.
On first impression, it does look like S. guaranitica. However, the leaves of Betsy's Choice are much larger and brighter; its nodes, or rooting points, are much farther apart. As to Amistad -- another South American species -- Betsy's Choice is far larger and much faster growing.
Another question is whether Betsy's Choice is the same plant as Salvia 'Betsy's Purple', which garden designer Bob Hyland of Portland wrote about for the Brooklyn Botanic Garden in 2003.
Information about the connections between Salvia species can be tantalizingly elusive. Our answer to all this botanical guesswork is that we don't have any answers.
What we do know is that this shoulder-high, long-blooming, water-loving perennial is heat tolerant and grows well in full sun or partial shade. And here's a footnote discovered at the Sweetbay garden website: Betsy's Choice looks terrific with a backdrop of Pink Muhly Grass ( Muhlenbergia 'Pink Flamingos').
